Sonar setting
In most cases, the default setting is enough. However, in some situations, to
get a better user experience, you need to adjust the menu setting.
o
Sensivity
Determines how echoes will be displayed on the screen.
Increasing the sensitivity will let you see more details on the screen. In deep
water, it is better to increase the sensitivity, whereas in the shallow it is
recommended to decrease the sensitivity.
o
Fish ID. Sens.
Fish ID. Sens. lets you adjust the threshold of fish size on display.
Selecting a higher setting allows any weak returns to be displayed as fish,
which is helpful especially when you are intending to find smaller fish species
or bait fish.
Selecting a low setting will prevent weak sonar returns being displayed as fish,
which will be very helpful when you are seeking large species of fish.
o
Gain
The gain controls the sensitivity of the hardware receiver.
A higher gain makes the sonar more sensitive to echo returns, allowing it to
display weaker targets. If the gain is set too high, the image might be cluttered
with some background noise.
Please note:
when set in [shallow water mode], the [Gain] option will be
disabled. It is used to get a better sonar performance in shallow water.
